Why are some users here using

**“In”**in place of ln or Ln for the functional notation for the natural logarithms?

$\displaystyle \begin{array}{l}

6\ln (x) = - 4 \\

\ln \left( {x^6 } \right) = - 4 \\

x^6 = e^{ - 4} \\

x = e^{ - \frac{2}{3}} \\

\end{array}$ - Aug 2nd 2008, 02:58 PMtutor
6lnx=-4

lnx= -4/6

lnx= -2/3

by the definition of logarithm

x= e^-2/3
